Application filed November 27, 1926.

This invention relates to a sled lister eultivator and it is an object of the invention to provide a device of this kind wherein the runners are provided at their forward .end portions with furrow openers together with a lever operating mecnanism readily ,Operable by the occupant of the seat of the .device for raisingv or lowering such openers as the occasion of practice may desire.

It is also an object of the invention to provide a device of this kind provided with a rear arch with which is adapted to be associated a ,ground working element or elements together with a mechanism readily operable by the occupant of the seat of the device for raisingr or loweringr such arch as may be desired.

Another object of the invention is to provide a device of this kind including a vertically adjustable or swingingr rear arch with which is operatively engaged a plural ity of drag hoes together with means whereby said hoes may abe laterally adjusted one with respect to the other as the necessities of practice may require.

The invention consists in the details of construction and in the combination and arrangement of the several 4parts of my im proved sled lister cultivator whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advan tageous Jfor use as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings` wherein:-m

Figure lO is a view in top plan of the plate engaged with the rear arch unapplied.

is illustrated in the accompanying drawings` l denotes the runners of a sled lister cultivator, each of which having engaged with the forward portion thereof an outstanding weed cutting blade or knife 2 eX- tendingn rearwardly on a predetermined outward incline, the under surface of saidblade being' substantially Hush with the under odge face of the runner l. Associated with the forward extremity of each of the runners l is a furrow opener or plow P comprisingr a plate 3 having its flat faces vertically disposed when in applied position. The rear of the plate 3 is provided with laterally spaced extension plates 4 which are adapted to receive therebetween the forward end portion of a runner l. These extension plates 4 are pivotally connected to said fforward portion of the runner l by the bolt 5 or the like whereby said opener or plow P is capable of swinging movement in a vertical direction.

To facilitate the requisite swingingr movement of the opener or plow P the outer lower `corner of each of the extension plates 4 is cut away`r as at 6` while the adjacentend of the runner is outwardly beveled in opposite directions. as at 7.

rlhe forward edge 8 of the plate 3 is disposed on a downward and inward curvature to facilitate the opener or plow P penetrating the soil. Extending upwardly :from the plates 3 are the arms 9 held to ,the outer faces of such plates by the bolts l0. The upper extremities of the arms 9 are continued by the inwardly disposed extension arms l1, one overlappingr the other. These extension arms ll areeffectively heldone to the other by the U-clamps l2 yof' a convenient type. The arms 9 with theirl ,eXtension arms ll, when assembled7 provide Lan upstanding arch member connecting the openers or plows P for unitary swinging movement in a vertical direction. The clamps 12 permit relative. edjustmentofthe llt) extension arms 11 to readily compensate for differing spacing between the runners 1.

Extending upwardly and laterally from the forward portions of the runners 1, and herein disclosed as secured to the upper edge faces of the runners 1, are the tables or platforms 14. To these tables or platforms 14 are bolted, as at 15, or otherwise secured the inner portions of the forwardly disposed and outwardly inclined strap' irons or rigid arms 16. To the outer extremities of these strap irons or rigid arms 16 are bolted, as at 17, the upstanding arms 18 continued at their upper ends by the inwardly disposed and overlapping extension arms 19. Selectively disposed through registering openings 2() in the extension arms 19 is a bolt 21. The arms 18 together with the extension arms 19 provide an arch member connecting the irons or arms 16 and the bolt 21 permits a relative adjustment of these extension arms 19 to readily compensate for the differing distances between the runners 1.

The bolt 21 is also disposed through the opposed legs 22 of a. downwardly facing hook member 23 straddling from above the overlapping portions of the extension arms 19 whereby an effective support is afforded for the forward end portion of a rearwardly disposed elongated arm 24. This arm 2t is of a length to terminate, as herein set forth, substantially midway of the ends of the runners 1 and the rear portion of the arm 24 is connected by the bolt 25 with an upwardly and inwardly inclined supporting member 26. There are two of these members 26, each secured to the table 14 by the bolts 15 hereinbefore referred to and said members 26 below the arm 24 are connected by the rigid bracing or reinforcing member 27 bolted, as at 28, or otherwise attached thereto.

The upper portions of the members 26 above the arm 24 are connected by the bolt 29 or the like and freely mounted on said bolt 29 and substantially snugly engaging between the adjacent end portions of the members 26 is a sleeve 30 carried by and arranged to one side of the boxing 31 to be hereinafter more particularly referred to.

Interposed between the runners 1 and the upper portions of the members 26 are the brace members or straps 32 the upper portions of which being secured to the members 26 by the bolts 25 and 25. These brace members 32 extend downwardly and rear,- wardly on a predetermined incline and are. bolted, as at 33, or otherwise secured to the runners 1.

Bolted or otherwise attached, as at 3'4, to the central portion of the arm 24 is an upwardly disposed arcuate rack 35 having an inwardly and forwardly depending extension arm 36 carried by the rear portion thereof. Pivotally engaged, as at 37, with this extension arm 36 is the lower end` portion of an upstanding lever 33 proviiled with a conventional latch mechanism 39 coacting with the rack 35.

The lever 38 is disposed through asleeve 4() provided with a forwardly disposed bracket 41 terminating in a laterally disposed barrel 42 through which is directed a bolt 43 or the like. rlhis bolt 43 has pivotally engaged with the extremities thereof the upper portions of the arms 44, the opposite end portion overlapping the inner end portion of an arm 45 pivotally held to the upper portion of the plate 3 by one of the bolts 10 liereinbefore referred to. The overlapping portions of the arms 44 and 45 are connected for adjustment one relative to the other through the medium of the bolt and socket connection indicated. at 46.

It is thought to be apparent that upon requisite operation of the lever 33 the openers or plows P will be raised or lowered when desired and that upon relative adjustment of the arms 44 and 45 the depth of peI1etration of the openers or plows P may be regulated.

In practice, the openers or plows P operate to open the grqund or to cut a furrow in advance of the runners 1 so that said runners will drop a desired extent below the normal surface of the land whereby the blades 2 hereinbefore referred to will be caused to work in the subsoil and thereby effectively destroy weeds and the like. This operation, as just stated, is particularly true when working on fiat land. When working in lister furrows the plows or openers P operate effectively to break clods or the like which may be within such furrows to assure the cultivator proper running steady and to the best advantage. the openers or plows P heilig adjusted downwardly in accordance with the extent to which said lister furrows may be filled.

The rear portions of the runners 1 are provided with the upstanding bearings 47 with which are engaged the outstanding trunnions 48 comprised in the upstanding rear arch 50. These trunnions 48 are relatively long in order to compensate for the relative adjustments of the runners 1 with respect to each other. The upper portion of the arch 50 is provided with the forwardly directed Uebracket 51 the side arms ol which being connected by a pin 52 or the li te.

Pivotally engaged with the pin 52 are the outer extremities of the parallel arms 53 constituting a forked portion of a bar 54. The bar 54 has secured thereto by the bolts or the like the upstanding arcuate rack 56. The rear end portion of this rack is provided with a downwardly and forwardly inclined extension arm 57 to the lower portion of which is pivotally connected, as at 58, the

'lll

lower extremity of an upstanding' lever 59. This lever 59 is disposed through the boxing 31 hereinbefore referred to. said boxing beinfr suitably held in a fixed position upon the lever 59. The lever 59 also carries a con ventional latch mechanism 6l!) tor eoaetion with the rack 56. l'lpon requisite swingingA movement of the lever ft the rear arch 50 may be raised or lowered as desired and such arch is locked in desired adjusted position by engagement of the latch mechanism (it) with the rack 56.

The seat S, as herein disclosed. is supported by the forked portion 53 ot the bar :34 and is held thereto in any pret'erred manner.

The side arms ot the arch 5U have clamped. as at 61, to the rear edge Jfaces thereot1 the bearing plates Gi. with which are operatively engaged the trunnions ('f carried by the forward portion of the plate tit-l. The plate G4 is disposed rearwardly ot' the arch and is mounted for swinginpr movement in a vertical direction. This plate 6l is adapted to have applied thereto any desired type of ground working implement but, as herein disclosed. there is pivotally connected, as at (i5, with this plate at transversely spaced points the rearwardly extendiimr beams 66. Each of these beams titl. as particularly illustrated in ltiaure t3. comprises spaced parallel members integrally connected at their outer portions by the interposed web 67 while their forward or tree end portions receive therebetween the plate (il. Contacting with the outer side edges of the beam 6G is the upper portion ot the vertically disposed standard G8 the lower portion ot' which having fixed thereto a drapr hoe (if) or other kindred implement. This standard 68 is also disposed through an eye member T0 havingy a shank Tl. This r-hank 71 is directed between the spaced parallel members of the beam titi and through the plate T2 bridging the space between said parallel members and contacting with the outer edge faces thereof.y as particularly illustrated in Figure S.

Threaded upon the shank Tl is the holding nut 'T3 which is adapted to have directy contact with the plate T2 to draw the eye member T0 inwardly ot' the beam 6G and thus effectively' grip the standard (i9 and particularly to hold the same between the notches T4- provided in the outer' edjfe faces of the parallel members ot the beam tt?. ln practice, these notches 'ill may be spaced as desired lengthwise ot the beam Gti so that the desired position ot the standard (it along the beam may be effectively maintained.

The web 67 has held thereto by the holding nuts 75 the forward portion of a rearvardly disposed elongated shank 76 having its outer or free end portion laterally directed. as at 77, and with which laterally directed portion is operatively' engaged a rod T8. This rod has its outer portion overlapping a second rod T9 and said rod 79 effectively coupled through the medium of U-elamps St). The U-clanips 90 permit relative adjustment of the rods 75% and T9 as may be required. The rod T9 is operatively engaged, as at 81, with the lower portion of an upstanding lever R2. This lever 82 is pivotally connected. as aty SJ. with an upstandingT bracket S4 secured to the rear portion otra runner l. said bracket being provided with an arcuate rack 85 with which coacts a latch mechanism carried by the lever 82.

The beams (it have their outer portions connected by a spreader Q7 whereby the beams are maintained in desired spaced relation and caused to have unitary lateral swinging: movement upon operation ot the lever 8i?. The latch mechanism 86 coacts with the rack 85 to hold the beams 66 in desired selective adjustment.

The spreader 9T comprises two members 9S havingr their inner portions in overlapping reltaion with their outer end portions t'reely engaged with the standards 68. The overlapping' portions ot the members S8 are :uljustably connected through the medium of a bolt and socket connection, as indicated at 89.

'lo further assure the runners Yl bein;r maintained in desired spaced relation and in parallelism. each ot' said runners has bolted, as at 90, to the outer face thereof the lower portion of an upstandii'ipj arm 9i the upper extremity of which being' continued by an inwardly directed extension arm 9:2. The extension arm ot' one arm 91 overlaps the. correspondinav extension arm of the second arm 91 and these extension arms 92 are connected one to the other through the medium of the U-clamps 93. These U-clamps 93 permit ready relative adjustment of the extension arms 92 in accordance with the required spacingY of the runners 1. The arms 91 are preferably carried by the runners l inwardly ot' the longitudinal centers thereof whereby ett'ective bracing' or reinforcement provided at the rear.

The runners l are preferably` of wood and for which reason l tind it of advantage to provide the side tat-es ot each ot the runners at the forward portions thereot' with the metallic wear plates .(l/lY to withstand the action of the, extension plates 4 comprised in the turrow openers or plows P.

The pin 52 also has engaged therewith a rearwardly directed hook member 95 with which may be engaged a chain or the like which, when operatively engaged with the beams 66 or their equivalent, will hold the same in a raised or inoperative position.

From the foregoing description it is thought to be obvious that a sled lister cultivator constructed in accordance with my invention is particularly well adapted l'or use by reason of the convenience and facility with which it may be assembled and operatedi and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carryingout my invention in practice except as hereirafter claimed,
